The HOBOnode Wireless Frost Alarm System, which combines a wireless temperature sensor, receiver, and free software (web download) provides a simple, cost-effective way to monitor frost conditions.
The system can wirelessly transmit air temperature readings to a PC, and provide audible and visual alarm notifications via cell phone text messaging and email when frost conditions occur. The system also makes it easy for you to view current temperature readings, as well as temperature trends over time.
Features:
- Sensor transmits current field conditions to your PC
- Accompanying free software provides alarm notifications to your cell phone, e-mail, or PC.
- Up to 6 mile transmission range (with HOBOnode Repeaters)
- Additional Sensors can be easily added to a HOBOnode network
- A Mounting bracket and two zip ties are provided for both the HOBOnode Temp and HOBOnode Receiver
